TILE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 263,823, datedSeptember 5, 1882, .Application led J une 24, 1882. (No model.)

To all whom it may concern: y

Beit known that I, JOHN F. STEPHENSON, a citizen of the United States ofAmerica, residing at Edgar, in the county of Edgar and State ofIllinois, have invented certain new and useful Improvements inTile-lliaf'zhines; andI do hereby declare thefollowing to be a full,

clear, and exact description of the invention, such as will enableothcrsskilled in the art to which it appertains to make and use thesame', reference being had to the accompanying drawings, and to lettersor figures ot' reference marked thereon, which form a part of thisspecication.

My invention relates to mechanism for severing the oontinuously-tbrmedproducts ot' a brick or tile machine-into separate articles; and itconsists in certain features hereinafter described, and specifically setforth in the claim. g

Figure l is a plan, and Fig. 2 a side elevation, with portions removed,of a machine embodying my invention.l

A represents a framework adapted to'snpport the operative parts of, themachine, and B represents a hingedifranie provided with archedcross-pieces b and cutting-wires b', all of the usual construction. Thisframe is provided with hinges b2; which 'are adapted to oscillate aboutand slide upon the rod b3, secured to the frame A, as shown, whereby thecutting-frame just described may be opened and closed, raised andlowered, at different points relatively to the frame ot' the machine.

At G are secured to the top of the` frame cleats, which project aboveand over a sliding frame, and upon one of the longitudinal beams thereofis a graded scale, d, and one of the cleats U is provided with anindicating mark, d.

Within the frame is a series of rollers, E, which are grooved centrally,as shown.

By the construction described it will be seen that the frame D isadapted to slide longitudinally within and upon the frame-work, and' themeans for sliding the same consist of a 1e-v ver, F, pivoted to theframe-work at f, and connected by the rod f to the stud f2, which issecured to theframe D, and by means of the arched plate G, havingnotches g at its edge, theV distance to which the frame D is moved maybe determined or, in other words, the frame D may be moved as desired,and as indicated by the scale d and indicator d.

This being the construction ofthe machine, its operation is as follows:As the clay is delivered from the machine in the form ot' a continuousbrick or tile, as is common in the art, it often occurs that, even wherethecuttingframe B is adapted to slide upon the hinged rod, there is moreor less waste ot' material, in that a portion ofthe material severed into bricks or tiles is less in length than the entire brick or tile.

' By my construction the point of severance` of the preceding number ofarticles, bricks, or tiles may be brought directly over the spacebetween any two ot' the rolls E by adjusting the table during itsreception of the continuous tile or after the feed of the same hasceased, and then independently sliding the cutterframe so that the endsevering-wire, b', shall coincide wit-h theleading end of the continuoustile. rlhe cut is made without waste, and a successive length ot'continuous tile is fed upon the rolls, and by a slight adjustment of thebed the last cut-that is, the leading end of the continuous tileiscaused to project beyond the roller and over the space between two ofthe rolls, and Vthus the cuttingframes brought to position as before,anda second seriesotl articles is produced without waste.

Having described my invention and its operation, what I claim, anddesire to secure by Letters Patent, is

'lhe combination of the frame A, provided with the cleats C, one ofwhich bears the indicating mark d', with the frame` D, provided 4withthe scale d, the studfz, rodf, lever F, and the notched plate G,substantially as shown and described.l

In testimony whereof I affix my signature in presence of two witnesses.

JOHN E. sTEPHENsoN.
